Brooklyn District Attorney’s Office

Investigators said the owner of a Brooklyn maraschino cherry warehouse shot and killed himself Tuesday, as he was being questioned on an environmental issue by investigators who later smelled marijuana.

Brooklyn District Attorney Kenneth Thompson’s office announced Monday that he will exonerate Derrick Hamilton, who served 21 years in prison on a wrongful conviction after saying he was framed by an allegedly crooked police detective.

Under a new policy announced Tuesday, most of the thousands of people arrested on first-time, low-level marijuana charges will likely no longer be forced to go to court for cases that are often eventually dismissed anyway.
